Patent number: 11944864Abstract: A motor brake device of an exercise apparatus includes a motor, a brake device and a lifting device. The brake device has a rotating disc and a magnetic brake mechanism. The rotating disc is coaxially mounted on a motor shaft of the motor. The magnetic brake mechanism has at least one magnetic portion. The lifting device is configured to drive the magnetic brake mechanism to move between a first position where the magnetic portion is located close to the rotating disc and a second position where the magnetic portion is located away from the rotating disc. The second position is located higher than the first position. When there is no electric power supplied to the exercise apparatus, the magnetic brake mechanism can move downward to the first position to stop rotation of the motor shaft by gravity due to potential difference between the second position and the first position.Type: GrantFiled: November 30, 2021Date of Patent: April 2, 2024Assignee: Johnson Health Tech Co., Ltd.Inventors: Yung-Fa Wang, Mei-Yi Wu

Patent number: 11921612Abstract: In exemplary embodiments, a computer system detects performance anomalies for user computer services. Physical databases convert physical database KPIs into logical database KPI vectors for individual user services and individual time intervals. Physical application servers convert physical application server KPIs into logical application server KPI vectors for the individual user services and time intervals. Physical web servers convert physical web server KPIs into logical web server KPI vectors for the individual user services and time intervals. A KPI server combines the logical database KPI vectors, the logical application server KPI vectors, and the logical web server KPI vectors for individual time intervals into user service KPI vectors for the individual user services during the time intervals.

Patent number: 11797411Abstract: An anomaly service receives log data from nodes in a computing environment, which includes a sequence of information indicative of log messages produced by the nodes. The anomaly service identifies dominant patterns in the sequence of information that are representative of non-anomalous blocks of the log messages. Having identified the dominant patterns, the service is able to extract the non-anomalous blocks from the log data to reveal anomalous blocks that do not fit the dominant patterns. The service may then generate anomaly vectors based on the anomalous blocks, which can be distributed to the nodes to detect anomalies.Type: GrantFiled: March 16, 2022Date of Patent: October 24, 2023Assignee: Oracle International CorporationInventors: Fa Wang, Raymond Michael Ofiaza Ordona, Mei Yuan, Xintao He, Campbell Webb
